This is a state-by-state guide for collectors and general folk art enthusiasts to learn about the types of masked dances still carried out in Mexico's Indian and mestizo communities today. Close to one-hundred colour photographs of authenticated masks from the collection of the Museum of International Folk Art are presented, including finely carved pieces from the 19th century to simple face coverings made in the past ten years. The masked ceremonies are brought to life with documentary photographs showing masqueraders acting out their roles.
